We analysed 13,072 published Financial Ombudsman decisions linked to Nationwide Building Society. This page shows outcomes, complaint types and decision patterns without rating the firm.
More complaints doesn't mean worse service — big firms serve millions of customers, so they naturally show up more often. Win rates reflect the mix of complaint types a firm faces, not a quality score.
Across the full dataset, about 1 in 3 clear-result cases ended with the customer winning fully or partly (33.5%). For Nationwide Building Society, this page shows 22.9%.
